Much effort has been made by many to relieve, or eliminate the side loading of cylinders created as a result of misalign- ment. It is, of course, almost impossible to get perfect alignment and since the alignment of the cylinder has a direct bearing on its life, the efforts have been well worth while. A spherical bushing used by The Sheffer Corporation and most everyone else in the cylinder industry, for various applications, is excellent and serves a very useful purpose. It does, however, have some very definite limitations. First and foremost among these is its inability, with the limited space available, to take the loads that the cylinder is capable of producing. The second deficiency of the spherical bushing or bearing is that it is limited to a maximum misalignment of five degrees and can act as a complete hinge in one direction only. With the Sheffer UNI-LIGN most, if not all, of these limitations have been eliminated. For instance, fifteen degrees each side of center is a reasonable angular misalign- ment at the pins, at the cylinder clevis and the rod clevis, increasing by three times the capabilities of the spherical bushing, plus providing maximum load carrying capabilities. It is recommended that not more than a thirty degree maximum angle be used on the pins in the out-board end of the UNI-LIGN units. However, when lighter than maximum loads are encountered, as much as 90 degrees could be used with complete safety. All components, pins, UNI-LIGN and mounting brackets are designed to take maximum loading of the cylinder where pin sizes match that of the clevis mount cylinder. All matching accessories and clevis mounts for cataloged cylinders are catalog standard. Time saved in installation may very well pay for the entire cost of the application.
